Dr Pepper is a carbonated soft drink, and the second-most popular brand of soft drink in the United States.
Dr Pepper is claimed to contain 23 different flavors. The exact composition of these flavors is a proprietary secret of the Dr Pepper company, but fans of the soda frequently attempt to guess the drink's composition.
One list that is frequently distributed online includes almond, blackberry, black pepper, black licorice, caramel, carrot, clove, cherry, cola, ginger, juniper, lemon, molasses, nutmeg, orange, plum, raspberry, sassafras/root beer, and vanilla, Others claim tomato, birch, amaretto, rum, cardamom, and cinnamon. Rumors have circulated since the 1930s that Dr. Pepper includes prune juice but the company has officially denied it.
